TECHNICAL FIELD

The disclosure relates to the technical field of communication, and moreparticularly to a method for determining a length of feedback responseinformation and a related product.

BACKGROUND

Hybrid Automatic Repeat request (HARQ) integrates storage,retransmission requesting and merging demodulation. That is, a receivingparty, in case of a decoding failure, stores received data and requestsa sending party for data retransmission, and the receiving partycombines retransmitted data with the previously received data and decodethe combined data.

A new radio (NR) system supports dynamic indication of HARQ timing. In atechnical solution of HARQ timing, a length (i.e., number of bits) of anAcknowledgement (ACK)/Negative Acknowledgement (NACK) fed back withinone transmission time unit (for example, one slot) is unable to bedetermined. Therefore, multiplexing transmission of an ACK/NACK isunable to be supported in an existing NR system.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the disclosure will bedescribed below in combination with the drawings.

Referring to FIG. 1, FIG. 1 is a possible network architecture of anexemplary communication system according to an embodiment of thedisclosure. The exemplary communication system may be a 5th-Generation(5G) NR communication system, and specifically includes a network-sidedevice and a terminal. When the terminal accesses a mobile communicationnetwork provided by the network-side device, the terminal may establisha communication connection with the network-side device through a radiolink. Such a communication connection manner may be a single-connectionmanner or a dual-connection manner or a multi-connection manner.However, when the communication connection manner is thesingle-connection manner, the network-side device may be a Long TermEvolution (LTE) base station or an NR Node B (NR-NB) (also called agNB). When the communication manner is the dual-connection manner (whichmay specifically be implemented by a Carrier Aggregation (CA) technologyor implemented by multiple network-side devices) and the terminal isconnected with multiple network-side devices, the multiple network-sidedevices may include a Master Cell Group (MCG) and Secondary Cell Groups(SCGs), data is transmitted back between the cell groups throughbackhauls, the MCG may be an NR-NB and the SCGs may be LTE basestations.

In the embodiments of the disclosure, terms “network” and “system” areoften used alternately and their meanings may be understood by thoseskilled in the art. A terminal involved in the embodiments of thedisclosure may include various handheld devices, vehicle-mounteddevices, wearable devices, computing devices or other processing devicesconnected to wireless modems, which have a wireless communicationfunction, as well as User Equipment (LTE), Mobile Stations (MSs),terminal devices and the like in various forms. For convenientdescription, the devices mentioned above are collectively referred to asterminals.

Referring to FIG. 2, FIG. 2 is a structure diagram of a 5G NR network.As illustrated in FIG. 2, there may be one or more. TransmissionReception Points (TRPs) in an NR-NB, and there may be one or moreterminals within a range of the one or more TRPs. In an NR systemillustrated in FIG. 2, for Downlink (DL) data, a terminal needs to feedback to the gNB through HARQ whether the DL data is successfullyreceived, i.e., the terminal is required to feed back a HARQ ACK/NACK tothe gNB. In the NR system, HARQ timing of ACK/NACK feedback informationfor data (mainly the DL data) may be dynamically indicated by the gNB,and the following transmission time unit is, for example, a slot.Referring to FIG. 2A, FIG. 2A is a schematic diagram of a transmissiontime unit for HARQ timing in an NR system. There may be made such ahypothesis that the HARQ timing is indicated in a slot n. As illustratedin FIG. 2A, there is made such a hypothesis that the HARQ timing may befive slots, and in the five slots, the slot n carries DL data for DLtransmission, the slot n+1 carries UL data for UL transmission, the slotn+2 carries DL data, the slot n+3 carries DL data, the slot n+4 is emptyand the slot n+5 is a slot through which the terminal feeds back anACK/NACK to the gNB. Since both the slot n+2 and the slot n+3 carry theDL data, the ACK/NACK corresponding to the slot n+2 and the ACK/NACKcorresponding to the slot n+3 are also required to be fed back. Forexample, if the gNB dynamically indicates that HARQ timing for theACK/NACK corresponding to the slot n+2 is three slots and HARQ timingfor the ACK/NACK corresponding to the slot n+3 is two slots, there areACK/NACKs of thee slots for the slot n+5, namely multiplexingtransmission of the ACKs/NACKs of the three slots is required to beperformed in the slot n+5. The terminal in the NR system illustrated inFIG. 2 cannot implement multiplexing transmission of the ACKs/NACKs ofthe three slots in the slot n+5.

In the embodiments of the disclosure, the terminal receives the maximumtransmission timing value sent by a base station, calculates a length ofthe feedback response information to be transmitted according to themaximum transmission timing value and sends the feedback responseinformation with the length to the base station. Therefore, multiplexingtransmission of an ACK/NACK within a transmission time unit may besupported by an NR system, and the advantage of supporting multiplexingtransmission of the feedback response information in the NR system isachieved.

Referring to FIG. 3, FIG. 3 illustrates a method for determining alength of feedback response information according to an embodiment ofthe disclosure. The method is executed by a terminal. As illustrated inFIG. 3, the method includes the following operations.

In S301, the terminal receives configuration signaling sent by anetwork-side device (for example, a base station). The configurationsignaling may include an indication about a maximum transmission delayfor feedback response information.

The configuration signaling in S301 may be transmitted by scheduling aPDSCH. Specifically, the maximum transmission delay may be indicated ina DL grant for scheduling the PDSCH. A transmission time unit is, forexample, a slot. There is made such a hypothesis that a firsttransmission time unit is a slot n, and the maximum transmission delaymay be the number of slots. Specifically, the maximum transmission delaymay be, for example, k1, and then k1 is indicated in a DL grant,scheduling the PDSCH, of the slot n.

In S302, the terminal dynamically determines an HARQ feedback timing.

An implementation method for S302 may specifically be as follows. Theterminal parses the configuration signaling to obtain the maximumtransmission delay, a transmission time unit delayed by the maximumtransmission delay from the first transmission time unit for receptionof the configuration signaling is a transmission time unit for HARQfeedback response information. Here, the transmission time unit is also,for example, a slot. If the configuration signaling is carried in a slotn for transmission and the maximum transmission delay corresponding tothe configuration signaling is k1, the determined HARQ feedback timingis k1, and the transmission time unit for the HARQ feedback responseinformation may be slot n+k1.

In S303, the terminal determines a length (i.e., a total number of bits)of feedback response information to be transmitted according to themaximum transmission delay.

In at least one embodiment, the terminal determines the total number ofbits of the feedback response information to be transmitted according tothe maximum transmission delay and a minimum transmission delay.

In at least one embodiment, the terminal determines the total number ofbits of the feedback response information to be transmitted according toa difference between the maximum transmission delay and the minimumtransmission delay.

In at least one embodiment, the terminal determines the total number ofbits of the feedback response information to be transmitted according tothe maximum transmission delay, the minimum transmission delay andM_(non-DL). M_(non-DL) is a value less than the maximum transmissiondelay.

In at least one embodiment, the terminal determines the total number ofbits of the feedback response information to be transmitted according toa value obtained by subtracting the minimum transmission delay andM_(non-DL) from the maximum transmission delay, and M_(non-DL) is avalue less than the maximum transmission delay.

In S304, the terminal sends a message containing the feedback responseinformation with the determined length of the feedback responseinformation to be transmitted.

An implementation method for the operation in S304 may specifically beas follows.

The terminal sends the feedback response information subjected to ajoint coding.

Or the terminal sends the feedback response information through aphysical channel.

According to the technical solution provided in the embodimentillustrated in FIG. 3, a base station, when scheduling a PDSCHtransmission, indicates the maximum transmission delay in a DL grant forscheduling the PDSCH of the first transmission time unit, and theterminal, after receiving the first transmission time unit, acquires themaximum transmission delay, calculates the length of the HARQ feedbackresponse information according to the maximum transmission delay andsends the HARQ feedback response information with the length to the basestation, so that multiplexing transmission of an ACK/NACK in atransmission time unit is supported in an NR system.

A technical effect achieved by the embodiment will be described belowwith an example. The transmission time unit illustrated in FIG 2A issent in the NR illustrated in FIG. 2. Herein, there is made such ahypothesis that each transmission time unit includes two TBs. If theterminal successfully receives the slot n and the slot n+2 and theterminal does not receive the slot n+3, for the existing NR system,feedback response information in the slot n+5 may be 1111. In theexisting NR system, if the terminal does not successfully receive thedata of the slot, no corresponding response may be fed back, so that theterminal may not contain the HARQ feedback response informationcorresponding to the slot n+3 in the slot n+5, and the base station maynot recognize, according to 1111, that the terminal does not receive theslot n+3. Therefore, the base station cannot accurately obtain the HARQfeedback response information of the terminal for subsequent operations,for example, data retransmission is unable to be performed according tothe HARQ feedback response information. According to the technicalsolution illustrated in FIG. 3, the terminal receives configurationinformation in the slot n, and the configuration information includesthe maximum transmission delay of 5 slots. The terminal determinesaccording to the maximum transmission delay that the total number ofbits of the HARQ feedback response information is 6 (the specific methodfor determining the total number of bits may refer to the followingdescriptions and will not be elaborated herein), then the terminal sendsthe 6 bit HARQ feedback response information in the slot n+5 and mayspecifically send 111100. The base station may learn according toallocation of slots for DL data that the slot n and the slot n+2 aresuccessfully transmitted and the slot n+3 is failed to be transmitted,thereby achieving the advantage that multiplexing transmission of anACKNACK in a transmission time unit is supported in the NR system.

In at least one embodiment, an implementation method for the operationin S303 may specifically be as follows.

The length, i.e., the total number of bits N, of the feedback responseinformation is calculated according to the following formula (1).

N=C*(T _(max) −T _(min))   (1).

C may be a positive integer, T_(max) may be the maximum transmissiondelay, and T_(min) may be a nonnegative integer not greater thanT_(max).

Tmin may be the minimum transmission delay for transmission of thefeedback response information by the terminal. Of course, Tmin may alsobe a parameter configured by the network-side device, and the parametermay be a fixed value. During a practical application, a value of Tminmay also be contained in the configuration signaling.

C may be a maximum number of bits of feedback response informationcorresponding to a PDSCH, car C may be a set constant (i.e., a valuespecified in a protocol or a value predetermined by a manufacturer), orC may be a parameter configured by the network-side device.

The maximum number of bits of the feedback response informationcorresponding to the PDSCH may specifically be: a maximum number of TBscarried in the PDSCH; or a maximum number of CB groups carried in thePDSCH.

For example, the maximum number of the TBs carried in a slot of thePDSCH may be 2 (the number is only for exemplary description and aspecific value of the number is not limited in the disclosure), thisdoes not mean that each slot includes two TBs, and in a practicalapplication scenario, the slot may include one TB or no TB (for example,the slot n+4 illustrated in FIG. 2A). The number of the CB groupscarried in a slot of the PDSCH may be 4 (the number is only forexemplary description and a specific value of the number is not limitedin the disclosure), and similarly, this also does not mean that eachslot includes four CB groups. A method for determining a value of N willbe described below with an example. Referring to FIG. 3A, theconfiguration signaling may be contained in the slot n, the maximumtransmission delay in the configuration signaling is 4 slots, and theminimum transmission delay in the configuration signaling is one slot.There is made such a hypothesis that a total number of basic units forthe feedback response information in each slot is two. The basic unitfor the feedback response information is, for example, a TB. Of course,during a practical application, the basic unit for the feedback responseinformation may also be a CB group, and the CB group includes at leastone CB. The value is determined to be 6 (bits) according to N=2*(4−1)=6calculated by using the formula (1).

The above technical solution docs not distinguish whether the feedbackresponse information between T_(max) and T_(min) is needed to be fedback to the base station. As illustrated in FIG 3A, the slot n+1 may beused to carry UL data, and for the slot n+1, no feedback responseinformation is needed to be transmitted to the base station. In thetechnical solution, the feedback response information corresponding tothe slot n+1 may be filled with a specific numerical value (for example,1 or 0), and the base station only needs to identify the feedbackresponse information corresponding to the slot n and the slot n+2, andmay discard or not process the feedback response informationcorresponding to the slot n+1.

In at least one embodiment, the implementation method for the operationin S303 may specifically be as follows.

The length, i.e., the total number of bits N, of the feedback responseinformation is calculated according to the following formula (2).

N=C*(T _(max) −T _(min) −M _(non-DL))   (2).

T_(min) and M_(non-DL) may be nonnegative integers. N is a nonnegativevalue, and meanings of C and T_(max) may refer to the descriptions inthe formula (1).

In at least one embodiment, M_(non-DL) may be the number of allfirst-type time units between a transmission time unit Y−T_(max) and atransmission time unit Y−T_(min), and a transmission time unit Y is atransmission time unit for transmission of the feedback responseinformation.

The first-type time unit may specifically include, but not limited to,one or any combination of a UL time unit, a time unit when the terminalperforms no transmission of a physical shared channel and a lime unitwhen the terminal does not monitor DL control signaling.

In the embodiment of the disclosure, in addition to determining thelength of the feedback response information by using the formula (1) andformula (2), another implementation manner may also be adopted todetermine the length of the feedback response information according tothe maximum transmission delay and the minimum transmission delay, oranother implementation manner is adopted to determine the length of thefeedback response information according to the maximum transmissiondelay, the minimum transmission delay and M_(non-DL). For simplicity,elaborations are omitted herein.

The method for determining the value of N will be described below withan example. Referring to FIG. 3A, the configuration signaling may becontained in the slot n, the maximum transmission delay in theconfiguration signaling is four slots, the minimum transmission delay inthe configuration signaling is one slot, and a UL time unit between aslot Y−4 and a slot Y−1 is the slot n+1, so M_(non-DL)=1. There is madesuch a hypothesis that the total number of the basic units for thefeedback response information in each slot is 2. Herein, the basic unitfor the feedback response information is, for example, a TB. During apractical application, the basic unit for the feedback responseinformation may also be a CB group, and the CB group includes at leastone CB. The value is determined to be 4 (bits) according toN=2*(4−1−1)=4 calculated by using the formula (2).

The above technical solution distinguishes whether the feedback responseinformation between T_(max) and T_(min) is required to be fed back tothe base station. As illustrated in FIG. 3A, the slot n+1 may be usedcarry UL data, and for the slot n+1, no feedback response information isneeded to be transmitted to the base station. According to the technicalsolution, information of the slot n+1 is not fed back in the feedbackresponse information.

Referring to FIG. 3B, FIG. 3B illustrates a method for determining alength of feedback response information according to a specificimplementation mode of the disclosure. A network device in theembodiment is, for example, a base station. The method is executedbetween a terminal and base station illustrated in FIG. 1. Transmissiontime units between the terminal and the base station is illustrated inFIG. 3A. As illustrated in FIG. 3B, the method includes the followingoperations.

In S301B, the base station sends configuration signaling to the terminalin a slot n, and the configuration signaling includes an indicationabout a maximum transmission delay (four slots) of feedback responseinformation.

In S302B, the terminal acquires the maximum transmission delay in theconfiguration signaling and dynamically determines an HARQ feedbacktiming to be four slots.
